(D) Fire When there is a new fire reception between the time of reception and the time of the output of the second timer, the representative fire light 40 blinks (or lights).
(E) A function to turn off the representative fire light 40 when there is no new fire reception from the time of receiving a fire until the time of outputting the second timer; Next, refer to the operation flowchart of FIG. The storage display control according to the present invention will now be described by taking as an example a case where a storage lamp 46 indicating that the storage operation is being performed is provided on the front of the receiver as shown in FIG.

Now, at the time of inspection, if the fire operation test switch among the operation switches 36a to 36n connected to the interface 34 is operated in order to confirm the accumulation time of the accumulation type fire receiver 10, the fire operation test switch A fire reception due to a simulated fire is determined in step S1, and the process proceeds to step S2, where a first timer T1 that sets a heat sensor accumulation time of 20 seconds is set.
And a second timer T2 that sets the accumulation time of the smoke detector to 50 seconds.
Is started.

When the timers T1 and T2 are started in step S2, the accumulation lamp 46 blinks in the next step S3, and the sensor line is temporarily restored.Next, in step S4, the timer T1 is reset to the accumulation time of 20 seconds. Is monitored to see if it has reached
If it is less than one second, the process proceeds to step S5 to check whether a new fire has been received, and repeats the routine of steps S3 to S5 to control the blinking of the accumulation lamp 46. If the storage time set in the timer T1 of 20 seconds is determined in step S4, the step
Proceeding to S6, the flashing accumulation lamp 46 is switched to lighting, and in the next step S7, the set time T2 of the second timer T2 = 50.
Check if it has reached the second, step if it is less than 50 seconds
Proceeding to S8, the presence or absence of a new fire reception is checked, and the routine of steps S6 to S8 is repeated until 50 seconds have elapsed.

In this embodiment, the CPU 2 was operated 50 seconds after the fire was received to perform both the fire operation test and the confirmation of the accumulation time of the smoke detector.
0 is the same control as when a fire is received again, and the accumulation light 46
During the lighting of, a new fire reception is determined in step S8, and the process proceeds to step S10, in which the storage lamp 46 in the lighting state is turned off, and a fire alarm display is performed in step S11. That is, the main sound device 26 is sounded and the display control unit 32
The representative fire light 40 and the district lights 42a to 42n connected to the light source are turned on.

By the display control of the accumulating light 46 at the time of the fire reception shown in the operation flowchart of FIG. 2, the accumulating light 46 blinks for 20 seconds from the fire reception, and the accumulating light 46 from 20 to 50 seconds. Will be lit, for example, by measuring the blinking time of the accumulating light 46 with a stopwatch etc., the accumulation time of the heat and heat sensor can be confirmed 20 seconds, and the accumulating light 46 blinks from receiving a fire, and further turns on The accumulation time of the smoke detector can be checked by looking at the stopwatch for the accumulation time of 50 seconds before switching off.

In the above description of the operation, since the fire operation test was also performed, a fire reception state was created at the time of output of the second timer in step S7 to display a fire alarm. However, an operation switch for measuring the accumulation time is separately provided. And test it.
After the output of the second timer, the process may proceed to step S9 to turn off the accumulation lamp.

When the storage operation is displayed using the representative fire lamp 40, the operation is basically the same as the operation flow diagram of FIG.
While the representative fire light 40 is flashing in step S3, or while the representative fire light 40 is lit in step S6, step S5 or S8
When it is determined that a new fire has been received, in the case of the accumulation lamp 46, the accumulation lamp 46 is turned off in step S10, but in the case of the representative fire lamp 40, the representative fire lamp 40 blinks or The difference is that the lighting state is maintained.

Incidentally, in the operation flow diagram of FIG.
The accumulating light 46 flashes until the second, and the accumulating light 46 is turned on from 20 to 50 seconds.On the contrary, the accumulating light is turned on from the fire reception to 20 seconds, and the accumulating light from 20 to 50 seconds. 46 may blink. This is the same when the representative fire lamp 40 is used.

Further, in the above-described embodiment, the representative fire light 40 is taken as an example of the fire light, but it is also possible to display that the accumulation operation is being performed by the district lights 42a to 42n. In this case, the display control during the accumulation operation by the district light corresponding to the alert line from which the fire was received is performed.

Further, in the above-described embodiment, the first timer and the second timer are started at the same time when a fire is received. However, the second timer may be started after the output of the first timer.

[Effects of the Invention] As described above, according to the present invention, when a fire operation test at the time of inspection or a fire reception in a steady monitoring state is performed, the storage lamp indicating that the storage operation is in progress is performed after the fire reception,
For example, it blinks for 20 seconds and lights from 20 seconds to 50 seconds, so you can check the accumulation time set for the heat sensor by the blinking time of the accumulating light, and smoke detection by the blinking and lighting time of the accumulating light. It is possible to check the storage time set in the detector, and since there is no need for a changeover switch to switch the storage time, the cost can be reduced by that much, and the heat detector and smoke detector can be replaced by one fire reception. Since the accumulation time can be confirmed, the operation of confirming the accumulation time is facilitated.

This point is the same when the storage operation is indicated by the district light instead of the accumulation lamp.In the display of the accumulation operation by the district light, it is not necessary to provide the accumulation lamp. The cost can be reduced by simplifying the receiver configuration, and the accumulated lines can be confirmed.
